Safety precautions for solder wire welding
Nov 08, 2022
11-08
2022
1. Improve welding technology, improve welding process and materials
Improve welding technology, realize mechanization and automation of welding operation, isolate people from welding environment, and fundamentally eliminate the harm of soldering operation to human body. By improving the welding process, it is avoided that the solderer welds in a container with extremely poor ventilation, thereby greatly improving the working conditions of the solderer; by improving the tin wire material, choosing lead-free and environmentally friendly tin wire is also one of the effective measures to reduce welding hazards.
How to choose the right solder paste in PCBA production
Nov 08, 2022
11-08
2022
Different products need to choose different solder pastes. How to choose a solder paste is an important problem to be solved in PCBA production. Now combined with relevant domestic and foreign standards, the inspection items of solder paste are introduced as follows. The selection of solder paste includes alloy composition, viscosity , effective working time, storage period.
The service life of environmentally friendly tin bars
Nov 08, 2022
11-08
2022
Now environmentally friendly tin bar products are widely used. However, because of its lead-free and environmental protection, the unit price of the product is expensive and the cost is high. A wave furnace needs about 500 kilograms of tin bars per tin furnace, that is, a large amount is invested each time, so the buyer will be careful.
Classification method of solder paste
Nov 07, 2022
11-07
2022
Solder paste is mainly used for the welding of electronic components such as PCB surface resistance, capacitors and ICs in the SMT industry. Solder paste can be divided into many types due to the production process, processing method and melting point.
1. According to environmental protection standards, it is divided into two categories: lead-free solder paste and leaded solder paste.
2. Dispensing solder paste and printing solder paste according to the tin method.
How to reasonably control the temperature when using solder wire
Nov 07, 2022

2022
Solder wire is a kind of filamentous solder. As we all know, solder wire is widely used now. Solder wire is mainly used for dip soldering and wave soldering. Electronic solder is the most consumed product today, and solder wire is also used for flame brazing and welding of large structural components and long seams. Solder wire is the most indispensable connection material in electrical and electronic products.
No-clean environment-friendly lead-free solder wire
Nov 07, 2022

2022
1. No-clean solder wire is a kind of solder wire. After the no-clean solder wire is soldered, the residue is not only very small, but almost no need to be cleaned.
2. Some of the flux of ordinary solder wire contains hydrochloric acid, which is easy to corrode the welding components such as circuit boards and pins, so it is troublesome and unsafe to clean the soldered places after welding.
Use of lead-free solder wire

2022
Solder wire is a fusible metal with a melting point lower than that of the metal to be soldered. When the solder is melted, the surface of the metal to be soldered can be wetted under the condition that the metal is not melted, and an alloy layer is formed at the contact surface to connect the soldered metals together. In general electronic product assembly, tin-lead solder, commonly known as solder wire, is mainly used.
Application of tin compound

2022
The classification, characteristics and application of electroplated tin, tin-lead alloy and tin-bismuth alloy are summarized.Electroplating lead-tin alloys have different components and different uses. For example, alloys with tin content of 5% to 10% are used for anti-friction coatings, alloys with tin content of 15% to 25% are used for lubrication and flux coatings, and alloys with tin content of 45% to 55% are used for seawater corrosion prevention.
Application of tin ingot

2022
Tin is a metal element, element symbol: Sn, belongs to the main group metal of IVA group, atomic number 50, relative atomic mass 118.71, belongs to IVA group metal, melting point: 231.89 ℃, boiling point: 2260 ℃, density: 7.28g/cm3 . Pure tin is soft, has good ductility at room temperature, stable chemical properties, is not easy to be oxidized, and often maintains a shiny silver luster. The content of tin in the earth's crust is 0.004%, almost all in the form of cassiterite (tin oxide), in addition to a very small amount of tin sulfide minerals.
Introduction to the uses and application areas of tin
Nov 03, 2022

2022
Tin is one of the earliest metals used by human beings, and it is also one of the metals with a wide range of industrial uses. It has excellent characteristics such as soft texture, low melting point, strong malleability, strong plasticity and non-toxicity. Alloys, chemical products, etc. It is widely used in electronics, information, electrical appliances, chemical industry, metallurgy, building materials, machinery, food packaging, atomic energy and aerospace industries. With the development of economy, its application fields will continue to expand. The specific application is as follows.
